update CI workflows to run 'apt-get update' if installation of packages via 'apt-get install' failed, likely due to stale apt cache

[Flamefire]

Sometimes we need to update the APT cache before installing to avoid:

E: Failed to fetch http://azure.archive.ubuntu.com/ubuntu/pool/main/d/dh-autoreconf/dh-autoreconf_17_all.deb  503  Service Unavailable [IP: 52.252.75.106 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

@Flamefire is there a reason you're reverting the switch from apt-get to apt (PR #4064)?

Using apt doesn't seem to be what you should be doing: It prints something like "unstable CLI, don't use in scripts" or so. At the least it is noise in the CI logs hence the switch

At some point we were probably running with Ubuntu 22.04 (because we were using ubuntu-latest), where apt does make sense, but not anymore since #4064 (we probably overlooked the "unstable CLI" messages when doing that)
